Can a virtual number send messages in a few hours?

Generally, you can send a virtual number directly by SMS within three or four hours. After more than four hours, the virtual number will be invalid, and you can't make calls and send text messages. Virtual number refers to the telephone number issued by a non-communication company, which is mostly a number sequence that is too long or too short than the conventional telephone number, but has the function of answering and making calls. Commonly used in skype and other platforms that provide VoIP services.
